Halfdan; a late 5th and early 6th century legendary Danish king of the Scylding (Skjöldung) lineage.

Halfdane was a legendary Danish king mentioned in various Old Norse sagas and poems. He is often associated with the Scylding dynasty and is considered the grandfather of Hrothgar, a key figure in the Old English epic Beowulf.

A Danish king Hroðgar appears in theAnglo-Saxon epics Beowulf and Widsith, and also in Norse sagas, Norse poems, and medieval Danish chronicles. In both Anglo-Saxon and Scandinavian tradition, Hroðgar is a Scylding, the son of Healfdene, the brother of Halga, and the uncle of Hroðulf. Moreover, in both traditions, the mentioned characters were the contemporaries of the Swedish king Eadgils; and both traditions also mention a feud with men named Froda and Ingeld. The consensus view is that Anglo-Saxon and Scandinavian traditions describe the same person.[

The poets within Beowulf sing about heroic deeds, battles, and the virtues of warriors. They sing to kings and nobles, usually to entertain and inspire them. The purpose of their performances is to commemorate the bravery and accomplishments of great warriors, preserving their legacy for future generations.
